請問下列這句英文的意思................

Question

because there likely is variation in residual disease activity ,it seems posible that the prognosis of cryptogenic cirrhosis also varies with the underlying etiology although this remains unclear.

Answer 1

由於疾病殘存的活性不同，所以不明原因肝硬化的預後也隨著潛在病因的不同而有所差異，雖然有時真正原因也不甚清楚。

Answer 2

Because there likely is variation in residual disease activity, 因為殘留疾病活動中極可能有變化，it seems possible that the prognosis of cryptogenic cirrhosis also varies with the underlying etiology although this remains unclear.雖然原因不明，似乎有可能肝硬化的『預後』，也會因為潛在病原的不同而有所差異。錯字： posible => possible

Answer 3

因為有可能是在殘餘的疾病活動上變化,it 似乎posible, 起因不明的肝病預測隨部下的原因論並且變化雖然這保留不明。
